systemd systemd-quotacheck@.service 8 systemd-quotacheck@.service systemd-quotacheck-root.service systemd-quotacheck File system quota checker logic systemd-quotacheck@.service systemd-quotacheck-root.service /usr/lib/systemd/systemd-quotacheck systemd-quotacheck@.service and systemd-quotacheck-root.service are services responsible for file system quota checks. They run once at boot after all necessary file systems are mounted. They are pulled in only if at least one file system has quotas enabled. systemd-quotacheck understands one kernel command line parameter: quotacheck.mode= One of auto, force, skip. Controls the mode of operation. The default is auto, and ensures that file system quota checks are done when the file system quota checker deems them necessary. force unconditionally results in full file system quota checks. skip skips any file system quota checks. systemd-quotacheck supports the service credentials logic as implemented by ImportCredential=/LoadCredential=/SetCredential= (see systemd.exec5 for details). The following credentials are used when passed in: quotacheck.mode The contents of the credential is parsed as same as the kernel command line option with the same name. See above for more details. Note that by default the systemd-quotacheck@.service and systemd-quotacheck-root.service unit files are set up to inherit quotacheck.mode credential from the service manager. systemd1 quotacheck8 systemd-fsck@.service8
