Re: [gentoo-user-ru] отключение флешки без umount

[Alex Efros]

Hi!

Всем спасибо за помощь. Вот, что получилось в результате:


--- /etc/udev/rules.d/99-usb-automount.rules ---

# Allow user mount/umount (set device owner and use 'owner' option in fstab).
# Create mount point directories for vfat/ext2/ext3/ext4/ntfs partitions.
# Create symlinks using partition label (overwrite duplicates).
# Auto-mount vfat with 'flush' option.
# No auto-mount for other filesystems (because there is NO SAFE auto-unmount).
# Auto-unmount vfat/ext2/ext3/ext4/ntfs and cleanup directories/symlinks.

P.S. В процессе отладки после частого подключения/отключения разных флешек
два раза что-то ломалось в ядре и оно переставало реагировать на
подключение/отключение флешек, приходилось перегружаться. Не думаю, что
это вызвано моими правилами udev, скорее это просто баг в ядре. "Умирало"
оно оба раза в момент подключения флешки, и последние сообщения в логе
касающиеся usb были примерно такие:

Не знаю, куда можно этот баг отправить, т.к. по желанию его воспроизвести
не получается. Да и ядро 3.2.11-hardened - далеко не последняя версия,
может в более новых это уже пофиксили.
