need for -user option for chroot

[Lars Nordin]

Hi,

I using busybox as part of a buildroot system and a want to chroot and 
chuid and the samt time, like chroot --userspec=USER:GROUP in GNU 
coruutils 8.5 (used in Ubuntu 11.4)

Anyone done this? (I using Busybox 1.17.4 as part of buildroot 2010.11)

Any comments? Sholad I use the same syntax or make the footprint smaller 
(ie chroot -u UID:GID will make the code smallest possible)

Regards,
/Lars
