kris> We really need to provide a better rc.conf hook for doing this -- kris> expecting people to write their own script just to create a /tmp kris> is lame. Here is just an example script (CAUTION: not well-tested) to create a filesystem/swap with mdconfig(8). This script support not only '/tmp by mdconfig(8)', but also replaces 'swapfile' variable of rc.conf with more generic way. Sorry no diffs for rc.conf(5) nor any comments of this script, but seeing is believing:) -- - Makoto `MAR' MATSUSHITA #!/bin/sh # # mdconfig(8) knob for /etc/rc # # Example: # mdconfig_filesystems='tmp swap' # # mdconfig_tmp_type='swap' # mdconfig_tmp_size='32M' # mdconfig_tmp_newfs_enable='YES' # mdconfig_tmp_newfs_flags='' # mdconfig_tmp_tunefs_enable='YES' # mdconfig_tmp_tunefs_flags='-n enable' # mdconfig_tmp_dir='/tmp' # mdconfig_tmp_mode='1777' # mdconfig_tmp_owner='root:wheel' # # mdconfig_swap_type="vnode" # mdconfig_swap_file="/swapfile" # mdconfig_swap_dir="swap" # # Note: # - No support of 'mdconfig -u unit'. # - No error checking of mdconfig(8). # for mdfs in ${mdconfig_filesystems}; do eval _type=\$mdconfig_${mdfs}_type eval _size=\$mdconfig_${mdfs}_size eval _file=\$mdconfig_${mdfs}_file eval _flags=\$mdconfig_${mdfs}_flags eval _newfs_enable=\$mdconfig_${mdfs}_newfs_enable eval _newfs_flags=\$mdconfig_${mdfs}_newfs_flags eval _tunefs_enable=\$mdconfig_${mdfs}_tunefs_enable eval _tunefs_flags=\$mdconfig_${mdfs}_tunefs_flags eval _dir=\$mdconfig_${mdfs}_dir eval _mode=\$mdconfig_${mdfs}_mode eval _owner=\$mdconfig_${mdfs}_owner case ${_type} in [Ss][Ww][Aa][Pp]) _args="-t swap -s ${_size}" ;; [Vv][Nn][Oo][Dd][Ee]) _args="-t vnode -f ${_file}" ;; [Mm][Aa][Ll][Ll][Oo][Cc]) _args="-t malloc -s ${size}" ;; esac _mddev=`mdconfig -a ${_args} ${_flags}` case ${_newfs_enable} in [Yy][Ee][Ss]) disklabel -r -w ${_mddev} auto newfs ${_newfs_flags} /dev/${_mddev}c >/dev/null 2>&1 ;; *) ;; esac case ${_tunefs_enable} in [Yy][Ee][Ss]) tunefs ${_tunefs_flags} /dev/${_mddev}c >/dev/null 2>&1 ;; *) ;; esac case ${_dir} in [Ss][Ww][Aa][Pp]) swapon /dev/${_mddev} ;; *) if [ ! -d ${_dir} ]; then mkdir -p ${_dir} fi mount /dev/${_mddev}c ${_dir} if [ -n "${_mode}" ]; then chmod ${_mode} ${_dir} fi if [ -n "${_owner}" ]; then chown ${_owner} ${_dir} fi ;; esac done To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
