I'm unconvinced because of the convoluted of the solution. But it's not a lot of work, on the contrary, the script is rather simple (
untested, is just an example):
Code:
#!/bin/sh
# Prepare the sandbox
mkdir /tmp/sandbox
mount -t tmpfs - /tmp/sandbox
mkdir -p /tmp/sandbox/usr/local /tmp/sandbox/bin /tmp/sandbox/lib /tmp/sandbox/card /tmp/sandbox/free
cp /bin/ipkg /tmp/sandbox/bin
cp /usr/lib/libipkg.so.0 /lib/libgcc_s.so.1 /lib/libc.so.0 /lib/ld-uClibc.so.0 /tmp/sandbox/lib
mount --bind /media/cf/ /tmp/sandbox/card
cd /tmp/sandbox/usr/local
for i in lib bin etc var share include home; do
ln -s /card/_local/$i .
done
ln -s /card/Programs programs
mount --bind /mnt/free/ /tmp/sandbox/free
# call ipkg
chroot /tmp/sandbox /bin/ipkg install /free/$1
# umount the sandbox
umount /tmp/sandbox/free
umount /tmp/sandbox/card
umount /tmp/sandbox
Clearly, it's not overly complicated (nor rocket science).
Beware: the paths I've used have been as I recall them, and the deps of ipkg are from OpenWRT, and I expect that it will need also tar and gzip to work.
So, coding it is not the difficult part. But... is it too convoluted?
