Re: run dselect for remote machine (nfs+chroot?)
I did experimented on this nfs+chroot approach. Following is my report:

I know the feeling. I used to run dselect on faster machine to find
a package and just run apt-cache/apt-get on slow machine.

Yes. apt-get pulls all the package listed in "suggests" which can be
avoided by dselect by putting them on "_", i.e., purge.
That is just classic "apt-get install". "apt-get upgrade", and "apt-get
dist-upgrade". New "apt-get dselect-upgrade" should honor setting by
dselect.
I nfs mounted all the slow machine files (/ /usr /tmp /var ...) as rw
from root account on a tree below /mnt using files exported by
(rw,no_root_squash,nohide). I "chroot" there and mounted proc of faster
machine to new /proc. dselect and "apt-get install" for slow machine
worked beautifully from the root account of faster remote machine.
dselect "select" had a great speed improvement in nfs+chroot environment
since I had a lot of memory on faster machine. But actual download and
install was very slower than expected because file moves through
networks between machines. From reading "top", nfs seems to consume CPU
heavily and network speed of 10 baseT was limitted (old 16 bit PCMCIA
card on slow PC can only do this speed even though network I have is 100
baseT.)
After all, mounting remote slow system to a faster machine. Then chroot
to there and run "dselect" to set selection. This is a good idea to
avoid memory swapping and slowness. Then I should have quited dselect
and run "apt-get dselect-upgrade" directly on the slow machine, I think.
Cheers ;-)
