Bug 105346 – dm-crypt-start cannot load libraries as called before /usr mounted

• Product: Gentoo Linux
• Status: RESOLVED INVALID

[Description Graham Murray 2005-09-09 01:00:34 UTC]

cryptsetup-luks installs the executable in /bin but the libraries in /usr/lib.
dm-crypt-start is called before partitions are mounted, so if /usr is on a
separate partition then cryptsetup is uncable to load the libraries. Copying the
libraries to /lib allows dm-crypt-start to run successfully.

Maybe these libraries, which are needed at boot time should be installed into
/lib rather than /usr/lib

Reproducible: Always
Steps to Reproduce:
1. Have /usr on a different partition than /
2. setup /etc/conf.d/cryptfs
3. Reboot

Actual Results:  
cryptsetup fails because it is unable to load shared libraries

Expected Results:  
cryptsetup to run without error and setup mappings for encrypted partition(s)

I have a warning in the ebuild that if you are using cryptsetup-luks for such a
purpose then you should have your USE=static. This will solve your problems.
