# Source Target FSType Flags CryptName Parallel
#
# The Parallel field controls mount ordering. Entries with Parallel=1 are
# launched concurrently with the preceding entries. An entry with Parallel=0
# acts as a barrier: all previously launched mounts must complete before it
# starts. This lets you express dependencies by position — for example,
# individual drives can mount in parallel, then a mergerfs union that depends
# on them uses Parallel=0 to wait.

/dev/sdb1 /mnt/sdb1 xfs defaults none 1
/dev/sdc1 /mnt/sdc1 xfs defaults sdc1 1

# Merged — waits for the parallel mounts above to finish before starting.
