Yesterday evening td123 and wonder were so nice to update the shell functions I wrote in order to make work with different packaging-chroots even more comfortable.

alias mktesting="upchr testing64 && mkchr testing64 && upchr testing32 && mkchr testing32"
alias mkstable="upchr stable64 && mkchr stable64 && upchr stable32 && mkchr stable32"

# Update the given chroot/all
function upchr() {
        if [ $1 = "all" ]; then
                echo -e 'e[1;32mUpdating the e[1;31mstable32e[1;32m chroot.e[0m'
                linux32 sudo mkarchroot -u /var/chroots/stable32/root/
                echo -e 'e[1;32mUpdating the e[1;31mtesting32e[1;32m chroot.e[0m'
                linux32 sudo mkarchroot -u /var/chroots/testing32/root/
