Hi,
just wanted to make change suggestion in pkgtools/mksandbox/files/mksandbox ( if there is any pkgsrc dev on this mailing list )
On line 456 :
ENV=/etc/shrc chroot \$sandbox /tmp/\`basename \$script\`
Chage this to :
ENV=/etc/shrc HOST=`basename \$sandbox\` chroot \$sandbox /tmp/\`basename \$script\`
By doing this, the "sandbox" script will automatically change the PS1 variable to the sandbox name instead of the host name each time you chroot into a sandbox.
