[MOD]user configurable userinit.sh V0.1.5.3 for CM. [UPDATED 9/05]

---

The purpose of this script to allow user to define their own set of configuration in a easier way. You can play with the parameters (user.conf)
to find out what suits you best.
Please check the third post for change log and rom compatibility list

  echo "Usage:"
  echo "/system/sd/userinit.sh [-s|-c config.file|-i]"
  echo 
  echo "Default:"
  echo "Sets system configuration based on the paratermers"
  echo "that listed in /system/sd/user.conf"
  echo 
  echo "  -s: check configuration status and cross" 
  echo "      verifiction with user configurations "
  echo "  -c config.file: use user parameters that defined"
  echo "                  in config.file "
  echo "  -i: Current system settings and info "

Install using ADB:

adb push userinit.sh /system/sd
adb shell chmod 755 /system/sd/userinit.sh
adb push user.conf /system/sd
adb shell chmod 755 /system/sd/user.conf
adb shell reboot

Install using terminal emulator
download the file and unzip it to your sdcard

su
mount -o remount,rw /dev/block/mtdblock3 /system
cp /sdcard/userinit.sh /system/sd
cp /sdcard/user.conf /system/sd
chmod 755 /system/sd/user.conf
chmod 755 /system/sd/userinit.sh
reboot

testing via ADB

adb shell sh /system/sd/userinit.sh -s

testing via terminal emulator

su
sh /system/sd/userinit.sh -s

-set cc_backingswap_en=0
-set linux_swap_en=1

To use only compcache without backing_swap
-set compcache=1
-set cc_backingswap_en=0
-set linux_swap_en=0
-set cc_disksize=32 (32*1024 = 32768kb = 32MB)

To use compcache with backing_swap
-set compcache=1
-set cc_backingswap_en=1
-set linux_swap_en=0
-set cc_disksize=0
-set cc_memlimit=8

To use compcache with linux swap
-set compcache=1
-set cc_backingswap_en=0
-set cc_disksize=32
-set cc_memlimit=0
-set linux_swap_en=1

To use compcache + backingswap with swap file
-set swap_file_en=1
-set linux_swap_file_size=32
-set linux_swap_file=/system/sd/swap.file
-set cc_memlimit=8
-set cc_backingswap=/system/sd/swap.file

To use compcache with linux swap file * Does not work
-set swap_file_en=1
-set linux_swap_file_size=32
-set linux_swap_file=/system/sd/swap.file
-set compcache=1
-set cc_backingswap_en=0
-set cc_disksize=32
-set linux_swap_en=1
-set linux_swap_partition=/system/sd/swap.file

Equivalent user.conf settings to CM 3.9.10+ compcache default settings

compcache_en=1
cc_disksize=24
cc_backingswap_en=0

Please do not use notepad to edit the user.conf or userinit.sh because you could end up some funny error due to format differences between unix and windows. A good example of unix format compatible editor for windows is notepad++

If you had any problem with the script please post the error log. This way its much easier to identify the problem

If there any other parameters/configurations that you wish to add, msg me! I will try to add them when i got time.

Which version of CM will this work for? The stable ones of the experimental also

If you upgrade from V0.1.1 to V0.1.3+ make sure you reboot your phone after install.

~ CC backingswap with swapfile does not work

Application upgrade or reinstall may causing force close as the odex file is incompatible. Please rerun the script to create the new odex.

thanks to uwonsum for pointing out these issues

I used the file from the thread for 3.6.7. whould u say urs is better. Even with my g1 overclocked and with compcache and it still lags little bit. Seedy for the find question u clearly state that its for 3.6.8.1. Was his wondering if it works with the experimental becuase not haveing compcache is a deal breaker.

Edit: are you sure about the experimental version because he said he is using a new kernal. S

Tried the script and my Android on CM 3.9.2 works smoothly. Checked with free on Terminal, seems to swap nicelly. What i don't get is the configuration... I downloaded the userinit.sh and user.conf, pushed to /system/sd and did the chmod stuff...

Do i have to change my user.conf to change the configuration? And what configuration works best for 3.9.2?

Nice work though! Finally after 5 months i had the guts to root and update SPL, recovery and mod my phone. Want to get the best out of it!

Ok, with the file in this post you have a compcache actived in swap partition without swap in CM ROM, thats correct?

And fixt the clock of CPU in MAX=528 and MIN=245, if i want to manage CPU status with set CPU what lines must to delete?

I only want to activate compcache in my 32mb swap partition, no swap, no CPU overcloack...

Thanks for your help and sorry for my english

For some reason this is the only one that word on the experimental builds...the others didn't work well even tho it said good compress 74 percent all the time..i would go to "tunewiki" cause that thing is the biggest memory hog, play some music see if it would load fast and then press back to go to the playlist...w/ compcache and swap off it would just go to a black screen and ask to wait or force close...but when the userinit stuff worked it would play stuff fast and go to the playlist without a hitch and no wait time...aka no killing the task in the background because of low memory....hurray..my compcache is working again..it might have had something to do w/ a .conf file...the others didn't have that file....hmmm, anyways thanks huanyu for this and whoever started playing w/ compcache in the first place!!! ha...

I have only test it with stable version of CM 3.6.8.1.

the by default, the 32MB of compcache is enabled. It should just work after you push the files to /system/sd

If there any other parameters that you wish to add, msg me! I will try to add them when i got time.

Very very nice, you basically re-wrote the whole thing from your original. Great work and thanks!

edit: The minimum usable cpu frequency is 128000, anything lower will cause the phone to freeze once power plug is removed.
here the available options:
19200
122880
128000
245760
384000
528000

I don't get it...what's the point of a config file for a config file?

jus to clairify to test it the command should be

adb shell /system/sd/userinit.sh -s

instead of

adb shell chmod 755 /system/sd/userinit.sh -s
