[gentoo-user] Public Apology to Minister Mentor Lee Kuan Yew and Prime Minister Lee Hsien Loong, Singapore
I was misconstrued as having insulted Minister Mentor Lee Kuan Yew. My words were twisted and misinterpreted and I feel that there is a need to explain myself and set the record straight. [b]What really happened[/b] It was sometime in Aug/Sep in the year 2009. The setting was in the Tampines Central office of Asiasoft Online Pte Ltd. I was having a ***verbal*** conversation with Melvin Lee, my new I.T. department manager, when he challenged me to complete an I.T. assignment within a specified period of time. In response to his challenge, I replied in Mandarin: If I cannot complete the I.T. assignment within a specified period of time, then Lee Kuan Yew is wang ba dan. I used to be fond of using other people's names to bet with people but now no more. The Minister Mentor's name came into my mind spontaneously and I used it to bet with my I.T. department manager. [b]Explanations[/b] 1. It was not my intention to insult the Minister Mentor at that time. Please note the use of the IF... THEN... statement in my verbal conversation. 2. I did not know wang ba dan [hanyu pinyin] means bastard at all until I consulted Goh Meng Seng much later. I would like to apologize to the Minister Mentor and the Prime Minister of Singapore if I have offended them in any way. I swear it was not my intention to insult the Minister Mentor. Please forgive me for using your name carelessly to bet with my former I.T. department manager. Yours sincerely, Singapore Citizen Mr. Teo En Ming (Zhang Enming) Dip BEng(Hons) Alma Maters: (1) Singapore Polytechnic (2) National University of Singapore

The other one doesn't have v4 set? Did you try modprobing NFS before trying your mount command? Unless you don't know what modprobe is, I shouldn't have had to ask this. You should have replied with `lsmod | grep -i nfs` (showing that the module is loaded) and a second attempt to perform the NFS mount. Stroller.

I rebuilt kernels on camille and catherine, enabling every NFS option I could and now they both can use NFS from carter. However, carter cannot mount camille's /mnt/store: carter ~ # mount camille:/mnt/store/ /mnt/store/ mount.nfs: requested NFS version or transport protocol is not supported But, somehow, carter has access to all the recordings. This happens sometimes and I don't know why...

I recently switched my three computers (carter, camille, and catherine) to the new gcc profile: i686-pc-linux-gnu-4.4.5 from i686-pc-linux-gnu-4.3.4.

Camille and catherine were a few hundred packages from the end of their emerge -e world when the power went out. Carter supplies daily updated /usr/portage to camille and catherine via nfs, but when I restarted the computers when the power came back on, I get this: camille ~ # mount carter:/usr/portage /usr/portage/ mount.nfs: an incorrect mount option was specified Am I not constructing my command correctly? I have tried mount -t nfs and it still doesn't work. I can ping carter fine, and carter says nfs is running. How do I get nfs back? I use nfs about twice/year to transfer large files between machines -- so I'm quite an expert at praying to the computer gods to please let this nfs mount work just this one last time and I'll never bother you again, I promise! I'm lying, of course, because I intend to do it again six months from now. Every time, the computer gods make me suffer through multiple attempts to guess the correct magic prayer before the remote nfs filesystem finally appears for its biannual visit on /mnt/nfs. Yes, I may well be paranoid, but it seems to me that the magic prayer for nfs mounts changes every time I need it. Sometimes I succeed using mount.nfs4, sometimes using mount -t nfs -o nfsvers=4, or sometimes just mount -t nfs. I have NFI what the real secret is, so I ask you nfs wonks to have mercy and fill us in...
