# emerge reiserfsprogs
fstab:
# NOTE: If your BOOT partition is ReiserFS, add the notail option to opts.
/dev/sda12 /boot ext3 noatime 0 0
/dev/sda10 / reiserfs noatime,notail 0 1
/dev/sda11 /var reiserfs noatime,notail 0 0
/dev/sda9 /home reiserfs noatime,notail 0 0
/dev/sda13 none swap sw 0 0
/dev/sda7 /mnt/sda7 ext3 noatime 0 0
/dev/sda8 /mnt/sda8 reiserfs noatime,notail 0 0
/dev/cdrom /mnt/cdrom auto noauto,ro 0 0
shm /dev/shm tmpfs nodev,nosuid,noexec 0 0
/dev/sdb1 /mnt/usbfs vfat noauto,user,exec 0 0
When booting...
* Checking root filesystem ...
Reiserfs super block in block 16 on 0x80a of format 3.6 with stand journal
Blocks (total/free):2664880/2147539 by 4096 bytes
Filesystem is clean
Filesystem seems mounted read-only.Skipping journal replay
Checking internal tree ... finished
* Remount root filesystem read/write
I want to ask why my root filesystem mounted as read-only,then remount.How to set my fstab to avoid it,to let it correctly booting?
Thank you!

 Its normal (non only on linux but BSD,unix,xenix,ultrix,aix and more others), in order to check and repair it correcly the root filesystem and to prevent corruptions at boot time is so, from a far past (~40 years).
If some others unoperative systems not do it, is another question.
For some special cases (root fs mounted on ramfs on a embedded system) you can override the default with a kernel parameter.

It is probably a good idea to set the pass option so that fsck is done at boot. Notice the last column numbers.
| Code: | /dev/sda12 /boot ext3 noatime 0 1
/dev/sda10 / reiserfs noatime,notail 0 2
/dev/sda11 /var reiserfs noatime,notail 0 2
/dev/sda9 /home reiserfs noatime,notail 0 2
/dev/sda7 /mnt/sda7 ext3 noatime 0 2
/dev/sda8 /mnt/sda8 reiserfs noatime,notail 0 2
/dev/sda13 none swap sw 0 0
/dev/cdrom /mnt/cdrom auto noauto,ro 0 0
shm /dev/shm tmpfs nodev,nosuid,noexec 0 0
/dev/sdb1 /mnt/usbfs vfat noauto,user,exec 0 0
