Bug#57712: Libc6 post-install fails on mounting /dev/pts

[Guus Sliepen <guus@sliepen.warande.net>]

Package: libc6
Version: 2.1.3

Error:
mount: devpts already mounted or /dev/pts busy
mount: according to mtab, none is already mounted on /dev/pts

Because of "set -e", the libc6.postinst script fails, and dpkg/apt-get
stops processing packages any further.

Suggested fix:
Add '|| true' to the line containing the mount command, or remove that
line (I don't really think it is necessary to have it there, /dev/pts is 
either already mounted at boot time or it is not, and in the latter case 
it probably is not wanted).

Met vriendelijke groet,
Guus Sliepen.
