Hi, there is a problem with the /etc/init.d/xmail file, it fails to copy lib files if they are listed in a specific way. I found this out after upgrading my glibc version and xmail segfaulting. I traced it down to an outdated ld-linux.so.2 in my /chroot/xmail/lib . This is caused by the sed filter from the init file that fails to copy the file. The output of ldd /var/MailRoot/bin/XMail: linux-gate.so.1 => (0xffffe000) libdl.so.2 => /lib/libdl.so.2 (0xb7fd0000) libpthread.so.0 => /lib/libpthread.so.0 (0xb7f7d000) libstdc++.so.5 => /usr/lib/gcc-lib/i686-pc-linux-gnu/3.3.5-20050130/libstdc++.so.5 (0xb7eb1000) libm.so.6 => /lib/libm.so.6 (0xb7e8c000) libgcc_s.so.1 => /usr/lib/gcc-lib/i686-pc-linux-gnu/3.3.5-20050130/libgcc_s.so.1 (0xb7e83000) libc.so.6 => /lib/libc.so.6 (0xb7d57000) /lib/ld-linux.so.2 (0xb7fea000) After applying the sed filter -n 's/[[:blank:]]*[^=]*=>\([^(]*\).*/\1/p', these files be copied to the chrooted lib directory: /lib/libdl.so.2 /lib/libpthread.so.0 /usr/lib/gcc-lib/i686-pc-linux-gnu/3.3.5-20050130/libstdc++.so.5 /lib/libm.so.6 /usr/lib/gcc-lib/i686-pc-linux-gnu/3.3.5-20050130/libgcc_s.so.1 /lib/libc.so.6 Clearly the ld-linux.so.2 library is missing. This is caused by the requirement that a line should contain a =>. This problem is solvable by using a slightly modified sed filter. Using sed -n 's/[[:blank:]]*\([^=]*\=>\)\? \([^(]*\) .*/\2/p;' the output will be: /lib/libdl.so.2 /lib/libpthread.so.0 /usr/lib/gcc-lib/i686-pc-linux-gnu/3.3.5-20050130/libstdc++.so.5 /lib/libm.so.6 /usr/lib/gcc-lib/i686-pc-linux-gnu/3.3.5-20050130/libgcc_s.so.1 /lib/libc.so.6 /lib/ld-linux.so.2 which is correct for my system. This script might break things if the ldd output lines without a => can contain weird stuff, I can't say because I'm no ldd expert. Reproducible: Always Steps to Reproduce: 1. Upgrading glibc 2. starting the chrooted version of xmail using /etc/init.d/xmail start Actual Results: XMail will not start because of a segmentation fault Expected Results: XMail should have started Fix supplied, needs verification concerning the ldd output
The fixed sed filter shouldn't contain a newline in it.

Fixed, thanks. Sorry it took a while, it's just no one here is using xmail. :/
