монтировать samba-файлы при загрузке с помощью systemd

У меня есть доля Samba, которую я хочу установить во время загрузки. Они ничего не нужны для чего-то немедленно, но я бы хотел, чтобы они были доступны, когда я впервые обращался к ним. Я попытался использовать файл .mount и запись в / etc / fstab с помощью специальной опции systemd. Проблема заключается в том, что DNS-резольвер не может разрешить хост файлового сервера, даже несмотря на то, что я заставляю модуль .mount зависеть как от текущей сети, так и от используемой системы. Я знаю, что могу просто зависеть от более поздней цели или добавить некоторую задержку, но мне интересно понять systemd и сделать это правильно.

One Solution collect form web for “монтировать samba-файлы при загрузке с помощью systemd”

Я закончил использование automounts, так что доля не смонтирована до первого доступа. Я решил отключить их после тайм-аута простоя, потому что время, необходимое для монтирования, обычно незаметно. Соответствующим вариантом в /etc/fstab является x-systemd.automount . Вот пример записи:

 //files.example.com/software /media/software cifs x-systemd.automount,x-systemd.idle-timeout=1min,rw,uid=jpkotta,gid=users,credentials=/etc/samba/private/files.cred,iocharset=utf8,file_mode=0644,dir_mode=0755 0 0
