[arch-releng] devpts problem

[Mr Green]

Had problems with lxterminal that I could not work out what was 
happening but error occurred after running build.sh

Before running ./build.sh devpts in mount looks like this

devpts on /dev/pts type devpts 
(rw,nosuid,noexec,relatime,gid=5,mode=620,ptmxmode=000)

Once build script starts to run devpts looks like this

devpts on /dev/pts type devpts 
(rw,nosuid,noexec,relatime,mode=600,ptmxmode=000)

Am assuming that the mount line in mkarchiso is the problem, ould be 
nice to find a way to restore defaults?
