Bug 567252

Description of problem:

Anaconda is using large file: 
/usr/lib/local/local-archive

Which is nearly 100MB large - it comes from glib-common package. However anaconda does not even have all the binaries and libs in the system - thus such file should  be generated to fit anaconda needs - i.e. files in /usr/share/local/ seems to be quite pruned having much smaller size - seems to  be installer selects only few of them to installation image - are they all?

Current solution does have several problems: file takes quite some space on the installation image. File is completely loaded into a memory when some process call 'mlockall()' and there are several such processes - lvm is amongst them. 

This basically leads to a situation the startup of any lvm command which modifies dm tables means mapping whole 100MB file into a memory.

There are several possible solutions for the problem:

- Detect all tools which are using mlockall() and use LANG=C for them - not really a good plan - but a pretty quick workaround.

- Try to make much smaller locale-archive file only for locale files which are really needed for anaconda installer - still might lead to maybe 20MB file??
(never tried - just a wild guess).

- Generate locale-archive according to locales given at the startup of installation - the best way - locale-archive should be in the range of hundreds KB, but probably requires some mount tricks to have the file generated probably in ramdisk shortly after installer asks for language.

Here is example of command, how the locale-archive file could be created:

localedef -i cs_CZ -c -f UTF-8 -A /usr/share/locale/locale.alias cs_CZ.UTF-8

Version-Release number of selected component (if applicable):
rawhide

How reproducible:
ls -la /usr/lib/local/local-archive
