CentOS6/RHEL6とCentOS7/RHEL7の/etc/login.defsの違い

CentOS6/RHEL6とCentOS7/RHEL7の/etc/login.defsの違いです｡

• CentOS6/RHEL6
Shell

# # Min/max values for automatic uid selection in useradd # UID_MIN 500 UID_MAX 60000 # # Min/max values for automatic gid selection in groupadd # GID_MIN 500 GID_MAX 60000

1 2 3 4 5 6 7 8 9 10 11

# # Min/max values for automatic uid selection in useradd # UID_MIN                   500 UID_MAX                 60000   # # Min/max values for automatic gid selection in groupadd # GID_MIN                   500 GID_MAX                 60000

• CentOS7/RHEL7

CentOS7/RHEL7ではシステムUIG,GIDの範囲を新たに追加されています｡

Shell

# # Min/max values for automatic uid selection in useradd # UID_MIN 1000 UID_MAX 60000 # System accounts SYS_UID_MIN 201 SYS_UID_MAX 999 # # Min/max values for automatic gid selection in groupadd # GID_MIN 1000 GID_MAX 60000 # System accounts SYS_GID_MIN 201 SYS_GID_MAX 999

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17

# # Min/max values for automatic uid selection in useradd # UID_MIN                  1000 UID_MAX                 60000 # System accounts SYS_UID_MIN               201 SYS_UID_MAX               999   # # Min/max values for automatic gid selection in groupadd # GID_MIN                  1000 GID_MAX                 60000 # System accounts SYS_GID_MIN               201 SYS_GID_MAX               999

UID,GIDの自動割当番号の開始が異なるのでデータ移行に注意が必要ですね｡
やはりUID=500から割り振られたアカウントは新たにUID=1000からに割り振った方がいいのでしょうか?
そうすると/homeをrsyncで同期後にUID,GIDの付け替えscriptが必要だな｡
