07:37:42 # Life 'Twas a good Debian birthday. Jingu-Gaien Hanabi Taikai last night celebrated the summer in a Japanese style with loads of fireworks. Instead of celebrating the summer, I personally celebrated Debian. This month's Tokyo area debian meeting is held this weekend. I'm looking forward to it.

22:31:07 # Life mount -obind and mount --bind. In Linux systems, you can mount a directory to a directory; and this is called bind-mounting. As far as I know, there are two syntaxes available for bind-mounting. One is mount -o bind /XXX /YYY and the other is mount --bind /XXX /YYY. I wondered how these two differ. I've checked the source and its operation, and it seems like they are equivalent. The source is in util-linux mount/mount.c. mount --bind /XXX /YYY is equivalent to mount -o bind -t none /XXX /YYY. Now that I know, I can happily write the entry to /etc/fstab. I was hoping to find a clue to 382977, but no luck so far.

11:15:47 # Life Big fan of sshfs. You can mount remote filesystems if ssh (sftp) works. Local commands can be used with remote filesystems. Handling too large files may cause network bandwidth problems, but it's useful. For example, Packages and Sources files, the index files for Debian packages, requires dpkg-scanpackages/dpkg-scansources to build. When the remote server isn't Debian based, it's a bit difficult to execute these commands on the remote server. Here comes sshfs. You can mount the remote filesystem, and use the commands locally.

$ mkdir remote
$ sshfs viper2:public_html/tmp/ remote
$ cd remote/20060731
$ dpkg-scanpackages . . > Packages
 ** Packages in archive but missing from override file: **

 Wrote 1 entries to output Packages file.
