[Clfs-dev] Changing gid's in clfs

[Martin Ward]

Hi Everyone

Just came across this issue of incorrect gid in the setup we use.

Since pt_chown is no longer installed by default , I was getting 
failures in dvtm(console terminal multiplexer) , I would get no bash 
prompt as a normal unprivileged user but worked fine as root

and hence applying to eglibc-2.18

At the moment we use a gid of 4, hence the problem

Solution move tty to a gid of 5, but this means moving tape's gid, I 
suggest 39  as that's the next free one.


Rather do this than install pt_chown as it is considered a security 
risk, what do others think
