Choosing group 141 as the next available gid from /usr/ports/GIDs, create a dtrace group and add the userids used by dtrace-a= ble programs to it. I shall use postgresql96 as the example: ``` # pw group add -n dtrace -g 141 -M postgres # cat /etc/devfs.rules [userdtrace=3D10] add path dtrace/helper mode 0660 group dtrace # sysrc devfs_system_ruleset=3D"userdtrace" ``` Will result in ownership/permissions like so (may need a reboot): ``` # ls -la /dev/dtrace/ total 1 dr-xr-xr-x 2 root wheel 512 Jun 3 11:42 ./ dr-xr-xr-x 13 root wheel 512 Jun 3 11:42 ../ crw------- 1 root wheel 0x9 Jun 3 11:42 dtmalloc crw------- 1 root wheel 0x4 Jun 3 11:42 dtrace crw------- 1 root wheel 0x7 Jun 3 11:42 fasttrap crw------- 1 root wheel 0x8 Jun 3 11:42 fbt crw-rw---- 1 root dtrace 0x5 Jun 3 11:42 helper crw------- 1 root wheel 0x6 Jun 3 11:42 profile ``` Resulting in: ``` # dtrace -l -m postgres | head -10 ID PROVIDER MODULE FUNCTION NAME 69078 postgresql79451 postgres CheckPointBuffers buffer-checkpoint-done 69079 postgresql79451 postgres CheckPointBuffers buffer-checkpoint-start 69080 postgresql79451 postgres CheckPointBuffers buffer-checkpoint-sync-start 69081 postgresql79451 postgres FlushBuffer buffer-flush-done 69082 postgresql79451 postgres FlushBuffer buffer-flush-start 69083 postgresql79451 postgres ReadBuffer_common buffer-read-done 69084 postgresql79451 postgres ReadBuffer_common buffer-read-start 69085 postgresql79451 postgres CheckPointBuffers buffer-sync-done 69086 postgresql79451 postgres CheckPointBuffers buffer-sync-start ``` --=20 You are receiving this mail because: You are on the CC list for the bug.=
