OK, so now that I’ve installed slackware 12.0 on this TP600X I was thinking about how I might get on if I converted my T42 back to slackware. Surely there’d be a heap of packages I’d miss. Sure I could compile from source. I used to do that years ago when I ran Slackware on a few systems. The problem became that open source writers seemed hell bent on adding as many convoluted dependencies into their packages … that you could easily waste a weekend just trying to get some program to compile. Not fun.<\/p>\n
Then I thought, why not install debian in a chroot and run the more difficult packages from the chroot.<\/p>\n
There’s a few notes on the net about using debootstrap to install debian in a chroot, but here’s what I did:<\/p>\n
\r\nGet the debootstrap deb from http:\/\/packages.debian.org\/etch\/debootstrap\/all\/download.\r\nDon't be like me and get the tar.gz from debian. That didn't work for me even though\r\ndebootstrap is just a shell script\r\n\r\n cd \/tmp\r\n ar x debootstrap_0.3.3.2etch1_all.deb\r\n\r\nExtract it in your host system\r\n\r\n cd \/\r\n tar xvzf \/tmp\/data.tar.gz\r\n\r\nRun:\r\n\r\n debootstrapdebootstrap --arch i386 etch \/chroot http:\/\/ftp.debian.org\/debian\/\r\n\r\n echo \"proc \/chroot\/proc proc none 0 0\" >> \/etc\/fstab\r\n\r\n mount \/chroot\/proc\r\n\r\n mount --bind \/dev \/chroot\/dev\r\n\r\n cp \/etc\/hosts \/chroot\/etc\r\n\r\n chroot \/chroot \/bin\/bash\r\n\r\n chroot# > apt-get update\r\n\r\n chroot#> apt-get install locales\r\n\r\n chroot#> dpkg-reconfigure locales\r\n (choose your locale. Probably should choose one of the en_US ones as well)\r\n\r\nI want to run some X program, so I just install xterm to get all the dependencies installed:\r\n\r\n apt-get install xterm\r\n\r\nTo get X to work back to your parent slackware environment via a domain socket try:\r\n\r\nmount --bind \/tmp\/.X11-unix \/chroot\/tmp\/.X11-unix\r\n\r\nYou might have to create the \/chroot\/tmp\/.X11-unix first.<\/pre>\nThe main thing is to have those mounts set up before you chroot each time.<\/p>\n
I noticed after I did all that, that I could run xterm as root but not as a regular user. ie. After setting up all those mounts and going:<\/p>\n
\r\nchroot \/chroot \/bin\/bash\r\nexport DISPLAY=:0\r\nxterm\r\n<\/pre>\nThe above worked, but something like the following did not (assuming the user kernel already exists):<\/p>\n
\r\nchroot \/chroot \/bin\/bash\r\nsu - kernel\r\nexport DISPLAY=:0\r\nxterm\r\nxterm: Error 32, errno 2: No such file or directory\r\nReason: get_pty: not enough ptys\r\n<\/pre>\nIt turns out you need the \/dev\/pts thing mounted .I originally did it inside the chroot, but its easier if you do it outside it<\/p>\n
\r\nmount --bind \/dev\/pts \/chroot\/dev\/pts\r\nchroot \/chroot \/bin\/bash\r\nsu - kernel\r\nexport DISPLAY=:0\r\nxterm\r\n<\/pre>\n","protected":false},"excerpt":{"rendered":"OK, so now that I’ve installed slackware 12.0 on this TP600X I was thinking about how I might get on if I converted my T42 back to slackware.
