#
# In kernels <v3.17:
# - the 0x016f2818 @ 0x24 magic number indicates big-endian or
# little-endian (can't distinguish between BE-8 and BE-32)
# In kernels >=v3.17:
# - a new 0x04030201 @ 0x30 magic number indicates big-endian or
# little-endian, but doesn't distinguish between BE-8 and BE-32
# - the old 0x016f2818 @ 0x24 magic number is little-endian for

# Summary: Database file for mlocate
# Description: A database file as used by mlocate, a fast implementation
# of locate/updatedb. It uses merging to reuse the existing
# database and avoid rereading most of the filesystem. It's
# the default version of locate on Arch Linux (and others).
# File path: /var/lib/mlocate/mlocate.db by default (but configurable)
# Site: https://fedorahosted.org/mlocate/
# Format docs: https://linux.die.net/man/5/mlocate.db
# Type: mlocate database file
