======Minimal debian system on 512MB flash====== I'm currently building minimal debian system for my backup & samba server. I just happen to have 512MB brand new CF card and CF-to-IDE reduction. This is my story of how to get (fully) working debian system on it. * Install without any choices. This will install approximately 300MB system. Yey! (Also, you need to do the usual, ext2, noatime and this kind of stuff -- you can probably save some space by using smaller inodes/blocks) * Add internet mirrors. * Install stuff you really need: vim, less * Purge locales: apt-get install localepurge (this frees approximately 44MB, so its worth it!) * Remove some docs you don't use and don't install them anymore. You can do this by adding those lines to ''/etc/dpkg/dpkg.cfg.d/01-nodoc'' and removing them: path-exclude /usr/share/doc/* path-exclude /usr/share/info/* path-exclude /usr/share/man/??/* * Remove locale sources from /usr/share/i18n. You will end up by having only those (yeah, and you can blacklist the rest as above): ./ ./SUPPORTED ./charmaps ./charmaps/UTF-8.gz ./locales ./locales/en_US ./locales/en_GB ./locales/iso14651_t1 ./locales/iso14651_t1_common ./locales/iso14651_t1_pinyin ./locales/i18n ./locales/translit_combining ./locales/translit_neutral ./locales/translit_circle ./locales/translit_cjk_compat ./locales/translit_cjk_variants ./locales/translit_compat ./locales/translit_font ./locales/translit_fraction ./locales/translit_hangul ./locales/translit_narrow ./locales/translit_small ./locales/translit_wide Alternatively, you can just comment every line in /etc/locale.gen and hope it won't break anything, or tell the system to use C locale.. Haven't tried that. * Now you should have place for anything else... apt-get install samba (and the space is gone like that.. puff!) * To get ro root, you need to mount these things as tmpfs (or use some overlay or what you like), so put this in ''/etc/fstab'': tmpfs /tmp tmpfs rw,nosuid,noexec,relatime 0 0 tmpfs /var/log tmpfs rw,nosuid,noexec,relatime 0 0 tmpfs /var/run tmpfs rw,nosuid,noexec,relatime 0 0 tmpfs /var/lib/dhcp tmpfs rw,nosuid,noexec,relatime 0 0 You will need to remount root after boot and before samba (TODO: Simple init script)
